Forums Not Showing Poster's Profile Info?

BBPress is integrated with Buddypress, and it creates the forum, and shows the forum perfectly. Including ‘Last updated by *user name* 13 hours ago. BUT once you actually enter the topic, it shows the topic creator’s postbit(avatar/role/time posted) fine, meanwhile showing all replies as ‘participant’ or ‘anonymous’ with no information shown. It shows their reply, but there’s no way of seeing who it is that replied.
